Relation of Serum Magnesium Level in Adult Patients with Idiopathic Generalized Epilepsy in a Tertiary Care Hospital.

Magnesium plays a vast role in the nervous system. In particular, high magnesium in cerebrospinal fluid appears to enhance the neural functions, while low magnesium induces neuronal diseases. The aim of the study was to find out the relation of serum magnesium with idiopathic generalized epilepsy attending in a tertiary care hospital. This cross-sectional comparative study was conducted in the department of Neurology at Mymensingh Medical College and Hospital, Bangladesh from January 2019 to June 2020 following ethical approval. Total 110 purposively selected participants (55 with idiopathic generalized epilepsy and 55 non epileptic apparently healthy individuals) were enrolled in this study. Serum total Mg was measured by EMP-168 Biochemical Analyzer. Average age of epileptic individuals was 33.13±9.5 years and majority was female (60.0%). Mean serum magnesium level was lower in epileptic patients than controls (1.80±0.041 vs. 2.02±0.19 mg/dl; p<0.001). Patients with higher seizure attack (>3 per month) had significantly lower mean serum magnesium level than the patients with seizure attack three or less per month. Serum magnesium levels are reduced in epileptic patients compared to healthy age and gender matched controls. Studies involving larger numbers of patients are needed to confirm these results.
